Osgood-Schlatter Disease

A concise overview of Osgood Schlatter disease and its treatment
 

This is defined as inflammation of the patella at its insertion point on the tibial tuberosity. Males are more affected than females. It typically occurs in boys between 12-15 years and girls at 8-12 years.

Mechanism

Caused by repetitive tensile stress on insertion of patellar tendon over the tibial tuberosity, which results in minor avulsion at the site and a subsequent inflammatory reaction. (tibial tubercle apophysitis)

Clinical Features

  • tender lumb over tibial tuberosity
  • pain on resisted leg extension
  • anterior knee pain exacerbated by jumping or kneeling, but relived by rest.

Investigations

Xray:

  • lateral knee: to visual fragmentation of the tibial tubercle with or without ossicles in the patellar tendon (very small bones, like the ones in the ear, see second image below)

Treatment

Benign: self limiting but does not resolve until growth halts.

Non-operative (majority):

  • Restrict intensive activities
  • NSAIDs with rest and both flexibility and isometric strengthening exercises.

Isometric exercise or isometrics are a type of strength training in which the joint angle and muscle length do not change during contraction

  • Casting if symptoms do not resolve with conservative management

Operative:

  • ossicle excision in refractory cases (done in patients with mature skeleton and persistent symptoms)
